We report the case of a 57-year-old woman who presented with local invasion of the anal canal by mucinous adenocarcinoma, the malignant transformation of a long-term preexisting retrorectal tailgut cyst. This progression is infrequent and justifies preemptive surgical treatment of retrorectal cysts.

Secondary chondrosarcomas according to malignant transformations of the solitary enchondromas were extremely rare in the hand. The aim of this study is to present a case of a 43-year-old male having rare malignant transformation of the solitary enchondroma treated with total excision and replacement with iliac bone graft.

Background: Nevus spilus is a rare, acquired, and often large cutaneous lesion consisting of a light brown background macule containing varying numbers of small darker macular or papular areas. Objective: Nevus spilus may contain dysplastic melanocytic elements, and there are also reports of melanoma arising from nevus spilus. However, the absolute risk for malignant transformation is not well defined. Conclusion: We discuss a case of synchronous melanomas arising from a nevus spilus and potential management recommendations based on a review of the pertinent literature.

Background. Abernethy malformation is a rare splanchnic vascular abnormality characterizing extrahepatic abnormal shunts that is classified into types I and II. Abernethy malformation type I has a female predilection and is associated with a variety of concurrent hepatic benign or malignant tumours while type II with concurrent tumours is very rare in females. Case Report. We report a rare female case of Abernethy malformation type II with concurrent occupying lesion in the right liver, which was successfully transplanted; the occupying lesion was pathologically proven to be nodular hyperplasia. Conclusion. This case might provide further knowledge regarding Abernethy malformation. On imaging, the anatomy of portal vein should be carefully investigated to categorize Abernethy malformation, and a wide variety of differential diagnosis of concurrent occupying lesions should be taken into account.

Objective. Endometriotic tissue implants rarely transform to malignant tissue, especially in a patient with a hysterectomy and bilaterally salpingo-oophorectomy. However, several cases with cancer arising from endometriosis after hysterectomy were reported in the literature. Hormone replacement therapy only with estrogen is a crucial risk factor for malignant transformation of persistent endometriotic tissue. Case Report. The present case demonstrates an endometrioid adenocarcinoma arising from persistent endometriosis tissue in a patient who was performed hysterectomy with bilateral salpingectomy 3 years ago. The histopathologic specimens of the previous surgery did not include any malignant tissue. After 3 years, she applied to the hospital with abnormal vaginal bleeding, and her histopathologic examination result found an ulcerated mass at the upper one-third of the vagina that is compatible with endometrioid adenocarcinoma. Conclusion. It is crucial to keep in mind the endometriosis history of the patient, to be able to diagnose cancer arising from endometriosis while evaluating the patient with a hysterectomy.
